TALLAHASSEE, Fla. (AP) — The Rev. Al Sharpton has led a group of several hundred people on a march to the state Capitol to protest Florida’s “stand your ground” law.

Among the people who joined them Monday were Trayvon Martin’s father and the family of Marissa Alexander, who was sentenced to 20 years for firing a gun near her estranged husband.

Florida law says people who are not involved in illegal activity have the right to stand their ground and meet force with force, including deadly force, if they reasonably believe it’s necessary to avoid death or great bodily harm.

Martin was fatally shot by neighborhood watch volunteer George Zimmerman, who later was acquitted of second-degree murder.

Marchers planned to attend House and Senate criminal justice committee meetings later Monday.
